Is there any reason to no use this in a Synology NAS?
Asked by: BIG AL
The WD 10TB Purple Pro 7200 rpm SATA III 3.5&quot; Internal Surveillance Hard Drive can be used in a NAS, but I would recommend the WD 10TB Red Pro 7200 rpm SATA III 3.5&quot; Internal NAS HDD, B&amp;H # WE102KFBXSPM, as WD Red drives are optimized for use in NAS arrays while WD Purple drives are optimized for surveillance.
